• There is a continuing switch from inorganic pigments to HPPs for quality and environmental reasons (for example, the ban in some applications of lead chromate pigments). In these applications there is also a growing demand for brilliant colors, and this leads to further replacement of the duller inorganics by organic pigments.
• Replacement of cadmium pigments and diarylide pigments is due to toxicological limitations in certain applications.
• Engineering plastics with outstanding technical properties need pigments with high heat stability.
• Highly sophisticated manufacturing machines are commonplace, so as to ensure a high output. Such machines require pigments with excellent heat resistance.
• Increased use of polypropylene (PP) fibers in the textile industry. PP-fibers are mainly ”dyed” with organic HPPs.
